FASTENING DEVICE.

Application filed January 23, 1922, Serial No. 581,982,

To all whom it 77266724] concern:

Be it known that I, BYRON SAMUEL VVAT- SON, a citizen of the UnitedStates, residing at Camden, in the county of Camden and State of NewJersey, have invented certain new and useful Improvements in FasteningDevices, of which the following is a specification.

One object of my invention is to provide improved means which can beconveniently and easily used to apply parts of snap fasteners or similararticles to cloth, garments or the like.

Another object is to so make my improved device that it can be readilyoperated by hand and will be positive and accurate in operation so as toprevent waste of material.

These objects, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawings in which- Figure 1 is a side elevation partlyin sec tion showing a device made in accordance with my invention,

Figure 14: is a View of the same general characteristics as shown inFigure 4 illustrating the attachment of a receptacle part of a snapfastener for co-action with the projecting part of the fastener forexample as shown in Figure 4.

Referring to the drawings, my improved device in the form illustratedincludes two jaws 15 and 16 which respectively have handles 17 and 18which are pivoted together at 19. The upper face 20 of the jaw 16 ismade flat and horizontal in the position shown in Figure 1; said jawbeing recessed at 21 to provide a shoulder to allow the setting of a dietable 22 which is rotatably mounted on a shouldered screw 23 which isscrewed downward into the jaw 16 so as to allow the die table to berotated for use in the application of fasteners of different sizes aswill be obvious from the following description.

The upper surface of the die table 22 at positions spaced apart withrespect to the axis of the table has a number of die recesses 24; thesedie recesses being of different diameters as shown in Figure 5. NViththe exception of the difference in diameters and difference in sizes ofthe associated parts of these die recesses they are all similarlyconstructed andhave similar features and in the following description itis therefore necessary but to describe one of these recesses and itsassociated parts and it will be understood that allof the recesses aresimilarly arranged and have similar acting parts adjacent thereto. Asshown in Figures 1, 2 and 4, the recess 24 which will be considered theactive recess has a hole 25 leading centrally downward from the bottomthereof.

A centering member 26, shown in detail in Figures 9, 10 and 11, has aring portion 27 which is situated in a cavity 28 which provides an uppershoulder at opposite sides of the hole 25 and a portion 29 of the metalof the die table 22 at each side of the hole 25 is bent upward intoembracing position so as to firml embed thecentering member 26 withinthe cavity 28. Two resilient tines or tongues 30 lead upward from thering portion 27 within upright channels 31 which are out in the dietable as shown in Figure 4. These channels 31 are diametrically opposedto each other as are also the tongues30 of to form a centering seat fora ball the centering member 26. The upper end portions of the tongues 30lead into the space provided by the recess 24 and these upper portionsof the tongues are provided with transversely extending grooves 32 for apurpose hereinafter described; the extreme ends 33 of said tonguesflaring slightly as shown in Figure 9.

The central hole 34 of the ring portion 27 of the centering member 26 isadapted which is mounted in a cavity 36 in the jaw 16; said ball beingpressed upward by a spring 37 as clearly shown in Figures 1, 3 and 4 sothat the ball tends to prevent accidental rotation of the die table onits pivot 23.

The jaw 15 includes an upwardly bowed portion 38 which terminates in adownwardly extending finger 39. The finger 39 has a hole 40' extendingupward from its flat end surface 41 and the axis of this hole 40, whenthe jaw is moved into the position shown in Figure 3, is in alignmentwith the axis of the die recess 24 which is immediately below it. Thehole 40 has portions of different diameters. For example, this hole hasa port-ion 42 of comparatively small diameter in which is slidable aretaining plunger 43; said retaining plunger having a head 44 at one endand at the opposite end being split upward from its extreme lower end toprovide tines 45 which tend to normally spread, as shown in Figure 8 toa diameter greater than the diameter of the portion 42 of the hole 40.However, when the plunger 43 is moved upward, as shown in Figure 3, thetines will be moved toward each other and the friction exerted will tendto hold the plunger in fixed relation relatively to the finger 39.

A coiled spring 46 surrounds the plunger and is partly located in aportion 47 of the hole 40 which is of greater diameter than the portion42 of said hole 40 so that the lower end of the spring 46 rests againsta shoulder 48 while the upper end of the spring 46 engages the undersurface or the head 44. The lower ends of the tines 45 taper downwardand inward so that when the tines are compressed they will provide acomparatively tapered structure such as shown in Figure 3. At a positionslightly upward from the extreme lower ends of the tines, the latter areprovided with grooved portions 49 which extend entirely around the tinesand are only interrupted by the split portions between the tines.

My improved device is particularly adapted for attaching snap fastenerportions to cloth, such as the cloth of garments, and as shown inFigures 1, 3, 4, 12 and 13, the snap fastener includes a button part 50and a back 51. The button part 50 has a central protrusion 52 and fourholes or slots the slots 53 extending through a plate or disk portion54; it being noted that when the part 50 is attached to a cloth or agarment, such for example as the piece of cloth illustrated at 55, thatthe protrusion 52 can engage within a receptacle of another part of thesnap fastener, such for example as the receptacle of the part 57illustrated in igure 14 so as to hold the two parts together in the wellknown manner of snap fasteners or liap buttons.

The back 51 out the snap fastener includes a plate ring portion whichhas piercing points 59 which are normally bent in the position shown inFigure 1; there being tour of these piercing points when the back is tobe used in conjunction with a button part similar to that illustrated at50; the piercing points being positioned annularly at equidistantpositions and are arranged at an angle to the plane of the ring portion58.

Tn the use of the device, one o1 the backs 51 is held by the retainingplunger 43 in the position shown in Figure 1 and to at tach the same itis merely necessary to depress the head 44 of the plunger so as to extend the split end portion of the plunger to allow the plate ringportion 58 to be slipped over the split end and find a seat in thegrooved portion 49 of the plunger. A release 01" the head 44 of theplunger will allow the spring 45 to slightly withdraw the plunger so asto move the plate ring portion 58 of the back 51 fiat against the endsurface 41 of the linger 39 of the jaw 15. The outer surface of thefinger 39 is pref erably provided with a registering marking, such forexample as the mark 60 shown in Figure 2, so that one of the points 5901the back can be moved into alignment with the mark 60; said mark beingso arranged as to be directly over a center line of one of the slots 53when the jaw 15 is moved toward the die table 22 by a coinpressingaction of the handles 17 and 18.

The cup or die recess 24 has its surface curving downward and inward sothat after the piercing points 59 are moved into engagement therewiththey will be compelled to follow the path prescribed by the grooveddeflecting surface of the die recess.

Considering that it is desired to attach one of the parts 50 to thecloth 55, said part 50 is placed with the orotrusion 52 e; tending downinto the hole 25 as shown in Figure 1 with the tongues 30 extendingthrough two diametrically opposed slots 53 with the peripheral edge ofthe plate portion 54 within the grooves 32. The diam eter of the. plateportion 54 of the part 50 is slightly less than the diameter of the dierecess 24 at its upper part so that when the jaw 15 is moved toward thedie table 22, the piercing points 59 will pierce the cloth and willextend into the recess 24 and llU will be deflected so as to pass aroundthe edge of the disk portion 54% "and upward slightly into therespective slots 53; thus turning the piercing points to produce hookswhich embrace the disk portion between the walls of the slots 53 and theperipheral edge of the disk portion 54.

In the actual and practical use of the device it has been found thatthis action can be quickly accomplished so that the, cloth will befirmly clamped between the back 51 and the part and the ends of thepiercing points 59 will be turned inward so as not to catch or injurethe hands or material with which the fastener comes in contact.

The receptacle portion of the fastener can be attached in the same"manner as the part 50 as shown in Figure 14 and in attaching thereceptacle portion a back is used similar to the back 51 abovedescribed; the receptacle port-ion having the slots which aresubstantially similar to the slots 58 above described in connection withthe part 50.

By rotating the die table, recesses of various diameters can be broughtinto operative position and in each instance the ball will serve toproperly center the die recess when it is moved into a position directlyover the ball.

While I have described my invention as taking a particular form, it willbe understood that the various parts of my invention may be changedwithout departing from the spirit thereof, and hence I do not limitmyself to the precise construction set forth, but consider that I am atliberty to make such changes and alterations as fairly come within thescope of the appended claims.
